How Will the Project Work?

The proposed project would convey and meter water from approved wells to the California Aqueduct. Most of these well facilities already exist; others will be installed. Water conveyance would be accomplished in one of two ways:

Conveyance directly into the California Aqueduct via private pipelines. Private pipelines will pump well water directly into the aqueduct. Flows into the aqueduct would be metered by WWD and verified by the California Department of Water Resources. Conveyance of water through the WWD laterals (pipes) may be used if the distance of privately owned pipelines proves to be impractical.

Conveyance through WWD laterals using reverse-flow meters. When direct conveyance into the aqueduct is not possible, groundwater may be conveyed from a participating well into a WWD lateral, with the flow reversed through the lateral to the aqueduct.

Pumping Pattern

The proposed project allows for water to be delivered through WWD facilities to the participants’ lands, the vast majority of which are in the southern two-thirds of the district. Pumping would occur mostly between the months of May and September. However, to provide flexibility in water supply, pumping and conveyance may occur in other months.

Approximately two-thirds of the water proposed to be conveyed in the aqueduct would be in lieu of local groundwater pumping in the delivery areas. The proposed project is limited to a maximum of 100,000 acre-feet per year of groundwater that may be delivered into the aqueduct during any single year. Because of water quality criteria and anticipated pumping restrictions, the actual annual volume of water conveyed may be less.
